About this map

The confluence of the Jefferson River, Madison, and Gallatin rivers creates a complex network of waterways and early settlements in the 1880s. This survey, conducted under the direction of J. W. Powell, illustrates the vital transport corridor where the Northern Pacific Railroad follows the northern arc of the rivers through Logan and Manhattan. The landscape transitions from the agricultural Jefferson Valley to the dramatic peaks of the Gallatin and Madison ranges, including landmarks like Gallatin Peak and The Sphinx.
